summary

I had a cold and fever a month ago. After the fever subsided, other symptoms gradually improved, but my throat has been itching, coughing, and a small amount of phlegm. It's OK during the day, especially at night. The more late in the night, the more serious the cough is. Not only can I not sleep well, but also the people in the same dormitory are affected by the bad rest. Next, I'll tell you about the reasons for coughing at night.

What is the cause of cough at night

Reason 1: cough is a reflex action of the human body to protect the body. Its main function is to remove the secretions of the respiratory tract. Therefore, cough is the main manifestation of respiratory diseases. If the cough is long-term and repeated, especially aggravated at night, it may be suffering from chronic bronchitis.

Reason 2: there are two main reasons for chronic bronchitis: one is external reasons, such as virus infection, cold air or dust stimulation to the upper respiratory tract, including allergic reaction; the other is internal reasons, including autonomic nervous dysfunction, respiratory immunity and defense function decline, as well as genetic factors.

Reason 3: after suffering from chronic bronchitis, we must first control the infection, sputum must be discharged, and the air in the living environment must be fresh and moist. Do not smoke, usually to strengthen exercise, improve the body's resistance, when the weather turns cold, to add clothing in time to avoid cold.

matters needing attention

When coughing, you should avoid eating fish, shrimp, fat meat and other foods that are prone to phlegm. Ginger, garlic, pepper and other spicy substances can stimulate the respiratory tract, so you should also pay attention to avoid them. Can eat fresh vegetables, such as a variety of vegetables, tomatoes, carrots and other vitamin rich foods are the first choice of cough patients.
